Hello all,
I am tryin to learn all this, it seems the default video mode is PAL,cuz I changed the image displayed,and it shows fine in pcsx2 ,which indicates it is running in PAL mode,but my ntsc ps2 rolls the image.
So which file and what do I change for the video mode?
Ive read the pdf,over and over,and im not clear still,it seems i should be using the gs init() function ,but not sure which file contains that. the gs.h?

p.s. i am refering to the example ps2tut_02a

In g2.c change

Code: Select all

gs_set_crtc&#40;NON_INTERLACED, v->ntsc_pal, FRAME&#41;;

to

Code: Select all

gs_set_crtc&#40;NON_INTERLACED, NTSC, FRAME&#41;;

This will hardcode the video mode to NTSC. As an alternative you can change the vmodes[] struct in the top g2.c

Recompiling the code might require some work, as the tutorials are from very beginning of ps2dev :-)
